I can't see posted images.

On some topics when someone posts a picture all I get is a small box with an x in it and "posted image" beside it. It is probably a firewall setting or something like that but I can't figure it out. I can see the pictures with my kindle, but not my home or work computer. Any ideas?

This may happen for various reasons, and it's not easy to tell why. Sometimes pics or accounts were deleted with only the dead links left, sometimes the particular cloud provider's server doesn't work, and there may occur temporary troubles with the web browser or web connection.

I experienced that when the problem persists, it's either due to a firewall setting, or the link is dead.
